The proportion
of injuries
that are head

Most blows to the head are
minor and nothing to worry
about, producing no symptoms
other than pain and perhaps
a small tender lump. However,
the Natasha Richardson case
highlights the fact that even
seemingly innocuous head
knocks can later produce
devastating effects. Warning
signs to watch for after any form
of head injury, no matter how
minor it might seem, include:
persistent headaches, balance
problems or cognitive changes.
If a head injury results in
a loss of consciousness,
increasing confusion, vomiting
or a worsening headache, the
person should see a doctor.
